Apparently... more people die every year by donkeys, then in plane crashes. To avoid death by a donkey, avoid donkeys, to avoid death by plane crash, avoid plan crashes! simple.

M4 is a single/3 round burst gun, it did not serve its role as a compact assault rifle for close quarters, so they made much greatness that is now known as the m4a1 which is so great it has automatic fire, and with that greatness came spray n pray.

M16A4 single/burst very accurate, moderate power, in close quarters, fix a bayonet, cuz you aint gonna hit crap with it.
